I just double checked to make sure I had the Bonus Tools for Maya 6 installed properly.

When I went to the Plug-In Manager and tried to load the 3ds Import plug-in I got this:

Error: Plug-in, "3dsImport.mll" was compiled against too old a version of the Maya API and is thus incompatible with the current Maya version. (3dsImport) //

Any ideas? Thanks.
